Aux. Power present Status:
1: The Aux. Power is present.
0: The Aux. Power is absent.
The value of this bit is fixed after each PCI reset.
Speed:
Set, when current media is 10 Mbps mode. Reset, when current
media is 100 Mbps mode.
Inverse of Link status:
0 = Link OK. 1 = Link Fail.
Transmit Pause Flag:
Set when the RTL8139C(L) sends pause packet.
Reset when the RTL8139C(L) sends timer done packet.
Receive Pause Flag:
Set when the RTL8139C(L) is in backoff state
because a pause packet received. Reset when pause state is clear.

GNTSel
Description
Gnt Select:
Select the Frame’s asserted time after the Grant signal has
been asserted. The Frame and Grant are the PCI signals.
1: Delay one clock from GNT assertion
0: No delay
Parameter Enable:
(These parameters are used in 100Mbps mode)
Setting to 0 and 9346CR register EEM1=EEM0=1 enable the
PHY1_PARM, PHY2_PARM, TW_PARM be written via software.
Setting to 1 will allow parameters auto-loaded from 93C46 (93C56)
and disable writing to PHY1_PARM, PHY2_PARM and TW_PARM
registers via software. The PHY1_PARM, PHY2_PARM, and
TW_PARM can be auto-loaded from EEPROM in this mode. The
parameter auto-load process is executed every time when the Link is
OK in 100Mbps mode.
